Don't be put off by the S6 badging on this Audi, says car spy Hans G. Lehmann, larger air intakes in the front bumper and the two ovalar exhaust pipes say this is the coming RS6, albiet in Avant form. According to the secretive Mr. H, the RS6 will get the same V10 as the S6, but producing in the range of 550 hp by way of a turbo setup. That kind of power will set it directly at odds with the BMW M5 and Merc E63 AMG. Oh yes, there will be a knifefight in Geneva next year.
